Ultrasonic velocities, viscosities and densities of binary liquid mixtures containing dimethyl carbonate and cresols (ortho, meta and para) have been measured at temperatures T= (303.15, 308.15, 313.15 and 318.15) K over the entire mole fraction range of dimethyl carbonate. The theoretical values of ultrasonic velocity were evaluated using Nomoto’s relation (UNR), impedance relation (UIR), ideal mixing relation (UIMR), Jungie’s relation (UJR), and Rao’s specific velocity relation(UR).The molecular interaction parameter (?) has been evaluated from the values of experimental and theoretical velocities. The experimental data of viscosity is used to test the applicability of semi empirical relations of various viscosity models like Grunberg–Nissan, Katti–Chaudhri, Heric–Brewer and Hind et al. for the systems studied. On the basis of the values of interaction parameters (d) of these viscosity models and interaction parameter (?) obtained from various velocity models ,the nature of molecular interactions between the components of mixtures have been explained.

The present study focuses on the role of remote sensing and geographic information system (GIS) in assessment of changes in vegetation cover, between 1973 and 2010, in the Salem revenue division, Salem district of Tamilnadu, India. The trend of vegetal cover changes over the time span of 37 years, was precisely analysed using Satellite images. The study revealed that the vegetal cover was 1325.99 and 1199.04 sqkm in 1973 and 2010 respectively. It was noticed that vegetal cover has decreased in 2010, because of the urban expansion led deforestation. It also revealed that the vegetal cover loss is due to expansion of cultivation and human interference. It is envisaged that the study would prove the usefulness of Remote Sensing and GIS in forest restoration planning.

The FT-IR and FT-Raman spectra of 2-hydroxy-4-methyl-3-nitropyridine (HMNP) have been recorded and analyzed. The optimized geometry, and harmonic vibrational wave numbers of HMNP have been investigated with the help of B3LYP scaled quantum mechanical (SQM) method supplemented with 6-311++G** basis set. The infrared and Raman spectra were predicted theoretically from the calculated intensities. The observed and simulated spectra were found to be well comparable.

The FT-IR and FT Raman spectra of 2,4-dihydroxy-3-nitropyridine (DHNP) molecule have been recorded in the region 4000-400cm-1 and 3500-50cm-1 respectively. Optimized geometrical parameters, harmonic vibrational frequencies and depolarization ratio have been computed by HF and density functional theory (DFT) using B3LYP/6-311++G(d,p) method and basis sets. The observed FT-IR and FT-Raman vibrational frequencies are analysed and compared with theoretically predicted vibrational frequencies. The calculated HOMO and LUMO energies shows that charge transfer occur within molecule. Unambiguous vibrational assignments of all the fundamentals was made using the total energy distribution (TED).

The present study was aimed to find out the relationship of marital adjustment between working and non-working married women. Sample of the study consisted of 100 working and non-working married women (working married women = 50, non-working married women = 50). Their age ranged between 25 to 46 years. Urdu Translation of Dyadic Adjustment Scale (Naseer, 2002) was administered to measure the Marital Adjustment of the entire sample. Results showed that that the non-working married women are better adjusted than working women. Working married women were facing more problems in their married life as compared to non-working married women; non-working married women are better adjusted than working women.

Medical diagnosis is very much essential for the human beings to survive. Earlier the diagnosis, lesser is the pain. The disease unattended will lead to extreme conditions and greater pain, loss of health and high expenditure. This paper focuses on the comprehensive scalability analysis conducted on two kinds of thyroid dataset: original and synthetic. The results obtained with original dataset consisting of 215 instances with 5 features have been compared with the results obtained with synthetic dataset consisting of 1075 instances with 25 features. Initially the features were reduced to 3 features and 13 features on both the cases respectively. Subsequently classification accuracy is obtained using top most performing classifiers namely C4.5 and Multi layer perceptron. The results obtained are promising and the dimensionality reduction technique has proved better for smaller datasets as well as for larger datasets.

The development of polymer solar cells has improved power-conversion efficiencies from 3% to almost 9% in recent progress. Based on semiconducting polymers, these solar cells are fabricated from solution-processing techniques and have unique prospects for achieving low-cost solar energy harvesting, owing to their material and manufacturing advantages. The potential applications of polymer solar cells are broad, ranging from flexible solar modules and semi transparent solar cells in windows to building applications and even photon recycling in liquid-crystal displays. The various device structures used in organic polymer solar cells are reviewed. The operating principles behind these devices are explained in order to provide the reasoning behind the different structures and bilayer and bulk heterojunction devices discussed.

Life skills have been defined as “the abilities for adaptive and positive behaviour that enable individuals to deal effectively with the demands and challenges of everyday life.”This paper examines the relevance of imparting life skills education in schools in today’s world, the core life skills, the target group those who most needs it; challenges and issues of adolescent students. And lastly emphasis is given on various methods to enhance life skills in students.

Living within a human community is a must for every human being upon which most scholars have agreed. The essentials of today’s life require presence of women within the community as well as men to work and do everyday activities. However, the street harassment issue as a social anomie for women is growing and their peace & comfort is taken away. Since this social anomie is a serious threat against the social security of people, so, the present research has been carried out to study the amount of street harassment for women and social elements affecting it in Iran. The methodology used in this paper was survey and the statistical community which is being evaluated is all youth between 18 and 28 among which, 280 individuals are selected randomly by the Cockron formula as the final cases. The results are analyzed using SPSS software. The results proved that there is a correlation between independent variables like age, education, monthly income of the family, relationship with the parents, monitoring and the control of official agencies and religious beliefs and the dependent variable of street harassment. Also the outcomes of regression analysis showed that %38 of changes in street harassment variable by means of the rest of six variables are defined in regression model and among those variables the relationship with the parents, age and education had the most effects on the dependent variable.

Good agricultural practices (GAP) are Practices that address environmental, economic and social sustainability for on-farm processes and result in safe and quality food and non-food agricultural products. In simple language, GAP stands on four pillars (economic viability, environmental sustainability, social acceptability and food safety and quality). In recent years, the concept of GAP has evolved to address the concerns of different stakeholders about food production and security, food safety and quality, and the environmental sustainability of agriculture. These stakeholders include governments, food retailing industries, farmers and consumers who seek to meet specific objectives of food safety, food production, production efficiency, livelihood and environmental benefits. Adoption of a sustainable practice means that the farmer has accepted the idea as good and that he intends to include it in the ongoing program of land preparation, planting, and harvesting. In other words, adoption is the implementation and continued use of an agriculture practice. This is an important difference from trial or experimentation, because a farmer might try a sustainable practice and abandon that practice. Adoption of sustainable practices by farmers is the key to transforming agriculture into a long-term, sustainable system. How far sustainability can be achieved in a democracy depends greatly on farmers’ voluntary acceptance of sound land use practices. Individual decisions are shaped by the availability of technical information and the appropriate machinery, seeds, and other inputs necessary to implement sustainable agricultural practices. This paper reviews literature on the good agricultural practices that promote sustainable food security.
